ELEVATOR ATTACHMENT.

Specification of Letters Patent;

Patented May 13, 1919.

application filed January 29,1919. Serial N 0. 273,766.

To all whom it may concern:

citizen of the United States, residing at of Maine, have invented certain new and useful Improvements in Elevator Attachments, of which the following is a specification.

This invention relates in general to elevators and specifically to a safety attachment for the elevator and a standing platform or floor thereadjacent.

One object of this invention is the production of an elevator attachment wherein corresponding supporting structures are provided at the edge of the elevator flooring. and also at the edge of the flooring of a supporting structure adjacent the elevator;

shaft, whereby whentheelevator descends ment of the elevator or near the floor of the supporting structure, the attachment will swing to release the" foot without injury thereto.

which is in the nature of a safety device for preventing a persons foot from being caught cates the flooryof. an elevator car and 6 the and injured or the person being held in position where he will be injured, in the event the elevator startswhile thefoot is protrudin where the movement of the elevator; will e ect the same. j

One practical formof construction and as sembly of the present invention will be hereinafter described and is illustrated in the drawing, in which Figure 1 is a top plan view of the elevator attachment showing how'the devices on the floor of the elevator and the floor of the sup porting structure cooperate with: each other.

Fig. 2 is a section taken'on the line 2-2 1 of Fig. 1. i

Fig. 3 is an enlarged fragmentary sectional view of a portion of the device taken on the line 33 of Fig. 1, and

Fig. 4 is a vertical section takenon the lineL-l of Fig. 3.

In the preferred embodiment of the present invention about to be described, indifloor ofa building or any other fixed support.

supporting structure are cut away to form The floor of the car and the floor 6 of the j i 1 thereby causing the inner edgesofthefloor 5 Be it known that I, ARTHUR G. LEBEL,

andthe floor 6 to be spaced apart as shown in Fig. 2. .Biddeford, in the county of York and State.

It might be stated that the construction of the safety device on the floor of the elevator car is identical with the construction of the safety device on the floor 6 of the supporting structure, and for this reason the description of the construction of one device will clearly illustrate the construction of the other device. Each floor is provided with a a reinforcing strip 8 adjacent the inner surface of therecess 7, thus preventing the floor from. wearing or breaking off where the point of strain bears thereon.

. bars 10 removably fit within the recesses and for, this reason extend substantially flush with the uppersurface of the floors, as shown inFig. 2. Eachbar 10 has a reduced porj 1 tion 11 at its inner end and. a pocket 12 is Another object of this lnvention 1s the 1 production of an attachment for an elevator floors and have eyes 14L at their upper ends fitting in the grooves 9 of the floors and extendrngtransversely to the grooves. These eyes fit within the pockets 12,. as shown clearly in Figs. 3 and l, andare held against displacement by the nuts 15 mounted on bars, s'uflicient space is provided for the actheir lower projecting. ends. 1 By providing the reduced portions at the inner ends of the commodation of the eyes 14 of the bolts, as is obvious from. an inspection of Fig. 1. With this construction it will be seen that the supporting bars 10 are pivotally mounted upon the floors and normally fit within the grooves.

A comparatively broad elongated supporting plate 16, which is only slightly smaller than the recessof each flooring is connected by the elements 17 upon the bars of each flooring. Thus a plurality of such, plates are employed and extendpar'allel and very near to each other. Since these plates are fixed' upon their respective supporting bars 10, each series of bars and its respective sup- "porting plate 16 constitutes the protector grating for purposes to be hereinafter set forth. t It should be noted that the bars 10 normally fit upon the. supporting strips 8 which are countersunk below the level of themner surfaces of the grooves 9. i

Very often, a persons foot may be projecting either beyondv the edge of the elevator car floor or beyond the edge of a supporting floor and when the elevator starts the persons foot is caught and jammed between the elevator and the supporting structure which not only often results in'serious injury to the foot or limb of such person but often throws the body of the person into position where he is seriously injured and sometimes fatally injured. In connection with the present device however if the elevator car is slightly below the level of the floor 6 of the supporting structure and a persons foot projects beyond the supporting plate 16 of the elevator car floor 5, obviously, downward movement of the elevator car will not cause the persons foot to be caught, although upward movement under ordinary'conditions would cause such action. In connection with the present invention however, the persons foot would strike the surface of the supporting plate 16 of the floor 6 and upon continued upward movement of the elevator car, the protector grating of the floor 6 would swing upwardly by the pivoting of the inner end of the bars 10 upon their respective bolts. As soon as thepersons foot is disengaged, the protector grating-would fall back down to its normal position. The same action would result if the person was standing upon the plate 16 of the floor 6 with his foot projecting beyond the plate. Downward movement of the. elevator car suddenly would cause the plate '16 of the floor 5 of the elevator car to be swung upwardly by the swinging of the bars 10, thus allowing the elevator car to :pass on down without injury to the persons foot or limb or body as above explained," as

soon as thepe rsons foot is disengaged, the

4 protector plate of the elevator car floor would'fall backdown to its normal position. Under normalconditions, the protector grating extends flush with the floors and a person may walk thereover without stum *bling or without interference from these gratings.

'The foregoing description and drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, mate- "rials, dimensions,-et cetera, as may prove'expedient and fall within the scope of the appended claims."

Having thus fully described my invention, what I claim as new and desire to secure' by Letters Patent is 1. In a device of the class described, the

' combination of an elevator Scar and a sup- 1 porting structure,-said car and structure havingcounter-sunk grooves formed therein, supporting'bars pivotally mounted'within said grooves, supporting platesfixedupon said bars, whereby said plates and bars normally fit flush with the surface of the elevator car and the supporting structure, although one or the other plates may swing when an article is in the path of movement thereof.

2. I11 a device of the class described, the combination of an elevator car and a supporting structure, said car and structure having counter-sunk grooves therein, bars fitting Within said grooves, said bars having reduced portions provided with sockets therein, bolts carried by said car and structure and having eyes .carried within said grooves and fitting within said sockets, thus pivotally supporting said bars, and supporting plates fixed upon the opposite ends of said bars, whereby if one or the other plate engages a protruding article, the plate and bars so engaged will be swung upwardly to disengage such an article without injury thereto.

3. In a device of the class described, the combination of a supporting structure and an elevator car having contiguous edges cut away to form elongated recesses, grooves formed in said car and supporting structure and extending inwardly from said recesses, bars pivotally mounted within said grooves, reinforcing strips carried adjacent the outer ends of said grooves, said bars restingupon said strips, supporting plates fixed upon the outer ends of said bars in alinement with said recesses, thus forming protector gratings, whereby when one grating is engaged by a protruding article, it will swing to disengage the article without injury thereto.

t. In a device of the class described, the combination of a supporting structure, and

- an elevator car having contiguous edges cut .combination of a supporting structure, and

an elevator'car, grooves formed in said car and supporting structure, bars plvotally mounted within said grooves, supporting 'plates fixed upon the outer ends of said bars, thus forming movable protector gratmgs.

6. In a device of the class described, the combination of a supporting structure and an elevator car, grooves formed in said car and supporting structure, bars positioned within said grooves, eye bolts carried within said grooves and engaging the inner end of said bars for pivotally supporting the bars remote from the forward edges of the supporting structure and car, and supporting plates fixed upon the outer end of said bars thus forming movable protector gratm s.

7 In a device of the class described, the combination of a supporting structure and elevator car, grooves formed in said car and supporting structure, bars positioned Within said grooves and having pockets in their inner ends, bolts having eyes positioned Within said grooves and being received within said pockets, thus pivotally receiving the bars in the grooves although the bolts Will be below the level of the car and supporting structure, and supporting plates fixed upon the outer end of said bars, thus forming movable protector gratings.

8. In a device of the class described, the combination of a supporting structure and elevator car, protector gratings pivotally mounted upon said car and said supporting structure at a distance from the outer edges of said car and structure although projecting beyond the outer edges, said gratings being countersunk below the supporting level of said car and supporting structure to prevent tripping thereover although said grating may be easily moved When necessary.
